MessageLogs can reside in data files, on specially allocated storage areas such as disks or memory, or output as raw I/O streams. In fact, a single Log may use each of these mechanisms to output or capture its contents. The LogInStorage association describes a Log located in a specially allocated portion of a StorageExtent. The offset of the Log, within the Extent, is defined using a property of the association, StartingOffset.
